Science
Mechanism of Action
This ingredient functions by creating a substantive, yet imperceptible, polymeric film on the skin's surface. This film contributes to the structural integrity and aesthetic feel of a formulation, and its presence can modulate the penetration dynamics of co-formulated active substances into the epidermis, thereby enhancing overall product performance.

Stability
While specific solubility data for this copolymer are currently unavailable, it is pertinent to note that structurally analogous polymers, such as Poly(glycerol succinate) (PGSuc), exhibit susceptibility to hydrolysis. This reaction can lead to a reduction in pH and the generation of carboxylic acid functionalities, particularly in acidic environments. Such pH-dependent degradation suggests a critical consideration for formulation stability and potential impact on active ingredient release profiles in low pH conditions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet evaluated GLYCERIN/SUCCINIC ACID COPOLYMER CASTORATE. However, its foundational monomers, glycerol and succinic acid, are classified as 'Generally Recognized As Safe' (GRAS) by the U.S. Food and Drug Administration (FDA) for various applications. Without specific data on the copolymer itself, the overall sensitization risk remains undefined.

Verdict
Given the limited specific research on GLYCERIN/SUCCINIC ACID COPOLYMER CASTORATE as a distinct entity, its overall utility beyond its established role as a film-forming agent requires further investigation, despite the recognized safety of its constituent monomers.
